One of the most important things that you need to pay attention to is the noise factor. Most of airbrush compressors are extremely loud, so you need strong nerves to withstand all that. More expensive and more sophisticated models do not have these problems, but the question is how much it's worth. You have to find a balance when it comes to your needs and budget.

Compression not only produces heat but squeezes water out of the air which ends up in the tank. Tanks can rust internally over time and if this is not controlled, the rusted air tank can eventually explode causing considerable damage and even death. That is why it is really important to evacuate the tank of water regularly. Most air compressors come equipped with a drain valve at the lowest point of the tank. If you dont want to spray water all over the floor under the unit, you may want to consider piping it from the valve to another place such as under the floor or into a drain. Piped water will flow uphill into a sink because it is being pushed out of the tank by compressed air.

Also, the portable air compressor is useful in hobbies like scuba diving. To make breathing underwater possible, an air compressor for scuba was made. This type of air compressor pump has made possible major breakthrough in the study of marine life. It has helped many adventurers explore the beauty of the sea.
